INHALER.

SPECIFICATION forming` part of Letters Patent No. 418,813, dated January7, 1890.'

Application filed J' une 1, 1889. Serial No. 312,868. (No model.)

To all whom it may concern.'

Be it known. that I, GEORGE L. MCQUIGG, a

'v citizen of the United States, residing at Flint,

in the county of Genesee and State of Michi'- gan, have invented acertain new and useful Improvement in Inhalers, of which thefollowing-isa full, clear,`and eXact description.

This invention relates to that class of inhalers which are adapted to becarried upon the person, and which are usually composed ot' a glass tubeprovided with an internal absorbentmaterial to receive and hold thesubstance to be inhaled.

The invention consists of atubular inhaler provided with an absorbentcore made, by preference, of asbestus and secured to a wire and betweentwo fibrous heads, the core `being by preference surrounded by a fillingof copper and zinc granules.

In the accompanying drawings, in the several iigures of which like partsare similarly designated, Figureil is an elevation; Fig. 2, a verticalsection; Fig. 3, a perspective view of the core and ibrous headsdetached; Fig. ha sectional end view, and Fig. 5 an elevation of amodification.

The tube a is made of glass, and by preference one end is made tapering,as at b, in order to concentrate the fumes or vapors.

f is a core made of suitable bibulous material, stiiened by a Wire d andarranged between brous heads e, the said Wire being anchored in or uponthe said heads, and thereby serving to hold and. keep the core and headstogether. Between the core and the interior of the tube is a filling c,composed of granules of copper and zinc.

l its retaining-its original form and size-that is to say, because ofits quality of not swelling or expanding upon absorbing liquid.

-The heads e are made of fibrous materialsuch as rattanin order topermit the free .Walls of the tube may be made parallel; and,

as also shown in said modification, cork-s g. may be provided to closethe ends of the tube to prevent evaporation. v y

The wire d may be omitted in some cases; but in that event the heads eeshould be made to tit the tube quite tight.

The filling c of metallic granules not only a'dds to the appearance ofthe inhaler, but in addition it supports the liquid to be inhaled in afree state.

Other filling c may be used than the rnetallic granules. Furthermore, afilling may be omitted altogether.

Instead of a tube of glass, any other substance or material may beemployed in the construction of the outer tube.

What I claim'isl. An inhaler composed of a glass tube, a bibulous corearranged therein,iibrous heads arranged at each end of said core andprovided with cavities e in their rims, and a lilling surrounding thecore between its heads, substantially as described.

2. An inhaler composed of an external tube, a bibulous core, fibrousheads at each end of said core, a wire passing through the heads andcore and connecting them, and an external iilling surrounding the core,substantially as described.

3t In an inhaler, a tube, a bibulous core composed of asbestus, andfibrous heads secured to the endsof said core, substantially asdescribed.

4. An inhaler composed of an external tube, a core of sheet asbestus,fibrous heads arranged at each end of the core, and a wirev connectingsaid heads and about which wire the asbestus is wound, substantially asdescribed.

5. An inhaler composed of a glass tube, a bibulous core, heads ateachend of said core, and a filling surrounding the said core, substantiallyas described. p y

In testimony whereof I have hereunto set my hand this '15th day ot' May,A. D. 1889.

GEORGE L. MCQUIGG.
